Failing to SetFilter of QFileSystemModel for .mp3/.avi files

[Stoned Jesus]

I need to traverse my drives in system and display only .mp3 and .avi files. basically set the filter to these extensions and display the files in a treeview.

@QStringList sDriveFilters;
QString sPath = m_SystemModel->fileInfo(index).absoluteFilePath();
ui->DriveListView->setRootIndex(m_SystemListViewModel->setRootPath(sPath));

sDriveFilters << "*.aac" << "*.wmv" << "*.avi" << "*.mpeg" << "*.mov" << "*.3gp" << "*.flv" << "*.mp3" ;

m_SystemModel->setRootPath(QDir::currentPath());
m_SystemModel->setFilter(QDir::NoDotAndDotDot | QDir::AllDirs );
m_SystemListViewModel->setFilter( QDir::Files | QDir::AllDirs | QDir::NoDotAndDotDot );

m_SystemListViewModel->setNameFilters(sDriveFilters);
m_SystemListViewModel->setNameFilterDisables(false);@

If you notice I have set filter as @setFilter( QDir::Files | QDir::AllDirs | QDir::NoDotAndDotDot )@

and setNameFilters to sDriveFilters. This displays all the directories in my treeview. Ideally I want it to display only audio/video files.
